The micro vibration motor can be divided into flat vibration motor and cylinder vibration motor. Flat vibration motor looks like a coin, belong to a dc motor, the motor shaft with an eccentric wheel, when the motor turns, the eccentric circle particle is not turn the heart of the motor, make motor is constantly out of balance state, caused by inertial effect. Cylinder vibration motor is composed of a motor and eccentric block, motor is a brushless dc micro-motor, brushless dc micro-motor or hollow cup motor, eccentric block connections on the motor shaft.
